Faruqi & Faruqi, LLP, a leading national securities law firm, is investigating potential claims against Quanex Building Products Corporation (“Quanex” or the “Company”) (NYSE: NX) and reminds investors of the November 18, 2025 deadline to seek the role of lead plaintiff in a federal securities class action that has been filed against the Company. Faruqi & Faruqi is a leading national securities law firm with offices in New York, Pennsylvania, California and Georgia. The firm has recovered hundreds of millions of dollars for investors since its founding in 1995. See www.faruqilaw.com. As detailed below, the complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose that: (1) the Company’s procedures and policies regarding tooling and equipment maintenance in its Tyman Mexico facility were significantly “underinvested”; (2) as a result, the Company’s tooling and equipment conditions had significantly degraded to near “catastrophic” levels; (3) that, as a result of the foregoing, the Company was likely to incur significant costs, “pushing out the timing” of expected benefits from the Tyman integration; (4) that Quanex had previously identified the foregoing issues; and (5) that, as a result of the foregoing, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis. On September 4, 2025, after the market closed, Quanex announced financial results for the third quarter of the 2025 fiscal year. Among other things, the Company disclosed “operational issues related to the legacy Tyman window and door hardware business in Mexico that are ongoing” which “impacted results more than expected during the third quarter of 2025.” Specifically, the Company reported a diluted EPS of ($6.04), compared to $0.77 in the prior year period and an adjusted EBIDTA of $70.30. The Company further disclosed that it was “adjusting for lower expected volumes and pushing out the timing of when [it] expect[s] to realize procurement savings” from the integration of the Tyman business. Then, on September 5, 2025, the Company held an earnings call pursuant to the Company’s third quarter 2025 financial results. During the earnings call, Chief Executive Officer, George Wilson (“Wilson”) explained “operational challenges” in the Tyman facility in Mexico “negatively impacted EBITDA in the Hardware Solutions segment by almost $5 million in the third quarter alone.” Wilson further explained that the issue was previously “identified midyear” as it got “deeper into the integration” with Tyman, and described how the systems used to “anticipate and plan for tooling repairs” were significantly deficient, indicating it was near “nonexistent.” Wilson stated because Quanex was “underinvested” in “the tooling condition and the equipment condition” it “had to make some changes and fix some things before it was catastrophic.” On this news, Quanex’s stock price fell $2.73, or 13.1%, to close at $18.18 per share on September 5, 2025, on unusually heavy trading volume. The stock price continued to decline on the subsequent trading day, falling $1.98 or 10.9%, to close at $16.20 per share on September 8, 2025, on unusually heavy trading volume.

When the true details entered the market, the lawsuit claims that investors suffered damages.

Faruqi & Faruqi is a leading national securities law firm with offices in New York, Pennsylvania, California and Georgia. The firm has recovered hundreds of millions of dollars for investors since its founding in 1995. See www.faruqilaw.com. As detailed below, the complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose that: (i) Jasper lacked the controls and procedures necessary to ensure that the third-party manufacturers on which it relied were manufacturing products in full accordance with cGMP regulations and otherwise suitable for use in clinical trials; (ii) the foregoing failure increased the risk that results of ongoing studies would be confounded, thereby negatively impacting the regulatory and commercial prospects of the Company’s products, including briquilimab; (iii) the foregoing increased the likelihood of disruptive cost-reduction measures; (iv) accordingly, the Company’s business and/or financial prospects, as well as briquilimab’s clinical and/or commercial prospects, were overstated; and (v) as a result, Defendants’ public statements were materially false and misleading at all relevant times. On July 7, 2025, Jasper issued a press release reporting updated data from the BEACON Study. The press release stated that “[r]esults from the 240mg Q8W and the 240mg followed by 180mg Q8W dose cohorts appear to be confounded by an issue with one drug product lot used in those cohorts, with 10 of the 13 patients dosed with drug from the lot in question,” that “[t]he Company is investigating the drug product lot in question and expects to have the results of that investigation in the coming weeks,” and that Jasper was “taking steps to ensure that drug product from the lot in question is returned to the Company and that sites have drug product from other lots to continue dosing.” Further, the press release revealed that the Company “has also determined that the drug product lot in question was used to treat participants enrolled in the ETESIAN [Study]. As a result, and in order to focus resources on advancing briquilimab in CSU, the Company is halting the study and pausing development in asthma.” Finally, the press release stated that “the Company is halting development in SCID” and, contrary to its prior representation of having a strong balance sheet and a cash runway extending “through the third quarter of 2025,” that Jasper “will be implementing a number of other cost cutting measures including a potential restructuring, to extend runway and reduce expenses.” On this news, Jasper’s stock price fell $3.73 per share, or 55.1%, to close at $3.04 per share on July 7, 2025.

Faruqi & Faruqi, LLP Securities Litigation Partner James (Josh) Wilson Encourages Investors Who Suffered Losses Exceeding $75,000 In Cytokinetics To Contact Him Directly To Discuss Their Options If you suffered losses exceeding $75,000 in Cytokinetics between December 27, 2023 and May 6, 2025 and would like to discuss your legal rights, call Faruqi & Faruqi partner Josh Wilson directly at 877-247-4292 or 212-983-9330 (Ext. 1310). Faruqi & Faruqi, LLP, a leading national securities law firm, is investigating potential claims against Cytokinetics, Incorporated (“Cytokinetics” or the “Company”) (NASDAQ: CYTK) and reminds investors of the November 17, 2025 deadline to seek the role of lead plaintiff in a federal securities class action that has been filed against the Company. Faruqi & Faruqi is a leading national securities law firm with offices in New York, Pennsylvania, California and Georgia. The firm has recovered hundreds of millions of dollars for investors since its founding in 1995. See www.faruqilaw.com. According to the complaint, defendants made materially false and misleading statements regarding the timeline for the New Drug Application (“NDA”) submission and approval process for aficamten. Specifically, defendants represented that the Company expected approval from the U.S. Food and Drug Administration (“FDA”) for its NDA for aficamten in the second half of 2025, based on a September 26, 2025 PDUFA date, and failed to disclose material risks related to the Company’s failure to submit a Risk Evaluation and Mitigation Strategy (“REMS”) that could delay the regulatory process. On May 6, 2025, during an earnings call, it was revealed that the Company had multiple pre-NDA meetings with the FDA discussing safety monitoring and risk mitigation but chose to submit the NDA without a REMS, relying on labeling and voluntary education materials. This confirmed defendants’ awareness of potential REMS requirements and their reckless decision to omit it from the initial submission, misleading investors about the regulatory timeline. As a result of defendants’ false and misleading statements, class members purchased Cytokinetics’ common stock at artificially inflated prices and suffered significant losses when the truth was revealed.
